A key limitation lies in the use of conventional reducing agents, which typically release low-boiling byproducts. These volatile species cause temperature fluctuations, leading to unstable reaction conditions that are detrimental in seeded growth strategies. In this work, we demonstrate that trioctylamine-alane (TOA-AlH3), a reducing agent with a high boiling point, enables the one-pot synthesis of InAs QDs with narrow excitonic absorption peaks extending up to 935 nm. Upon ZnSe shell growth, these QDs exhibit high PL quantum yields (QYs) of 75% and 60% at 905 and 1000 nm, respectively, which are record values for amino-As-based InAs@ZnSe systems. Moreover, TOA-AlH3 is applied in a seeded growth approach to prepare larger InAs QDs, achieving narrow excitonic absorption up to 1350 nm. After ZnSe shelling, these samples exhibit PLQYs of 46%, 38%, 32%, and 23% at 1160, 1250, 1335, and 1430 nm, respectively. Importantly, TOA-AlH3 is compatible with ZnCl2, a necessary additive for reaching high PLQYs. These advancements establish a robust and scalable synthetic route to highly luminescent InAs QDs, paving the way for their integration into next-generation infrared optoelectronic applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501512","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although Cr3+-doped zinc gallate nanoparticles (NPs) have been widely studied as in vivo bioimaging nanoprobes due to their NIR PersL emission at 695 nm, the simpler Cr3+-doped gallium oxide system has been less explored despite its deeper NIR emission (760 nm), which favors tissue penetration. This is likely due the lack of synthesis methods that render Ga2O3-based NPs suitable for in vivo applications. In this paper, a novel method for the synthesis of uniform and hydrophilic γ-Ga2O3:Cr3+ NPs is reported, whose photoluminescence (PL) and PersL are optimized by adjusting their Cr3+ content. Such properties are further greatly improved through an annealing process at high temperature, which result in the transformation of its crystal structure into the β-phase. The obtained β-Ga2O3:Cr3+ NPs are colloidally stable in a physiological pH simulator medium and are nontoxic for cells. Finally, this work studies, for the first time in literature, the in vivo biocompatibility of such NPs using a Caenorhabditis elegans (C. elegans) animal model, finding that their morbidity and reproductive toxicity are negligible. In summary, the reported NPs are excellent candidates for their use as a NIR PersL probes for in vivo bioimaging.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501422","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining QD-doped photopolymers with two-photon polymerization (2PP) enables the fabrication of fluorescent 3D complex objects with nanometric resolution. To avoid QD agglomeration, which would hinder the device's optical performance, different strategies for achieving homogeneous particle dispersion within the polymer matrix are analyzed. Notable approaches include surface modifications, dual-functional QDs serving as photoinitiators and fluorophores, and resin additives. Depending on the protocol employed, the QDs enable sub-wavelength resolution and precise structuring during the manufacturing, by interacting with both the photopolymer and the laser beam. These physicochemical phenomena are also systematically investigated. Finally, this review provides a comprehensive examination of the characteristics and applications of QD-based optical devices, including photoluminescent security tags and PUFs, QD-integrated photonic crystals (PCs), stimuli-responsive 4D sensors, multicolor metamaterials, near-infrared (NIR) filters, and light nanosources, including single photon sources. The fabrication strategies of plasmonic light nanosources are investigated as well. The various fabrication approaches for these devices are critically analyzed and systematically compared to highlight their respective advantages, limitations, and potential for future advancements.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202403288","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most existing perovskite light-emitting devices primarily employ direct current (DC) driving, alternating current (AC)-driven perovskite devices have garnered increasing research attention. Studies demonstrate AC driving has remarkable advantages in reducing operational voltage, enhancing luminous efficiency, improving device stability, and suppressing perovskite ion migration. Its low-voltage/low-frequency compatibility is expected to seamless integration with household power systems and wearable electronics. This review analyzes the carrier transport properties of perovskite materials under AC electric fields. Accordingly, the operating principles and processes of AC-driven perovskite light-emitting devices with three different structures are demonstrated. Moreover, AC driving strategies in perovskite light-emitting diodes, light-emitting transistors, and flexible displays are reviewed, with a focus on their performance implications. With this review, the aim is to deepen the understanding of the critical role of AC driving of perovskite light-emitting devices in overcoming the inherent limitations of DC operation. It is expected to outline the future trajectory of smart displays and flexible electronics based on AC-driven perovskite light-emitting devices to accelerate their transition from laboratory prototypes to commercial applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, ZnO/ZMO nanoparticles prepared via low-temperature sol–gel methods with small grain size and abundant surface defects always suffer from structural and electrical drift, causing lifespan reduction and performance fluctuations of devices. Herein, the benzyl phosphate (BPA) and its derivatives are introduced onto the surface of ZMO NPs as armor layer to stabilize and regulate their properties as ETLs. The prepared ZMO capped with BPA NPs have fine structural and electrical properties stability, which have simultaneously achieves effective defect passivation, enhances nanoparticle dispersibility and stability, and precisely tunes energy levels to balance charge injection. By benefiting from the robust ZMO ETLs, the overall performance of the QLED devices has been greatly boosted. The resulting external quantum efficiency (EQE) of green QLEDs is increased from 20.8% to 29.9%, showing the best performance among currently reported ZMO-based green QLEDs, and over 3.3-fold improvement in T95 operation lifetime at 1000 cd m−2.
